REMOTE POSTA~ TER INSPl~;CTION SYSTE~M
Backqround of the Invention
Postage meters are in common usage throughout the
business world because of their ability to save time and
allow an acc~unting of the amount of postage used. Psstage
meters are charged with monetary value upon payment to the
Post Office of a selected amount. This monetary value is
reduced as postage is applied to mail pieces. Because the
postage meter does contain monetary value, care must be
taken that no unauthorized postage impressions be made for
to do so would be defrauding the Postal Service. Various
security measures have been devised to prevent postage meter
tampering through which unauthorized postage could be
printed. Included in such sec~lrity measures are break away
screws, sealed housings, and the fact that postage meters
are leased by the user rather than being owned. To assure
that postage meter tampering has not taken place, the U.S.
Postal Service has a regulation that every leased postage
meter must be physically inspected at least two times a year
by the manufacturer of that postage meter. This requires an
inspector visiting the premises of the user to carry out the
inspection. Similar procedures exist in other countries.
The cost of such inspection is approximately $50.00 per
inspection or $100.00 a year for every installed postage
meter. With almost one million postage meters installed in
the United States, this amounts to a cost of approximately
cne hundred million dollars every year for postage meter
inspection.
Recently there have been two developments in the
postage meter field that are bringing about substantial
changes. One of the developments is a result of the
advancement of electronics which has led to the electronic
postage meter. The electronic postage meter is one in which
solid state devices instead of mechanical systems are used
for such purposes as memory and control. The second
development is the use of encryption for the purpose of
2 ~ 37S3
authenticating a postage indicia. It obviously would be
beneficial if these recent developments may be utilized
to reduce the need for the physical inspection of every
postage meter.
Summary of the Invention
A remote postage meter inspection system has been
devised whereby a postage meter may be programmed to
indicate the occurrence of any tampering or attempt to
obtain unauthorized postage. A postage meter is

polled periodically through a communication link. When
an act of tampering has been indicated, then the meter
would be either inspected physically or removed. An
alternative embodiment to this would be to have a
postcard imprinted with the postage indicia by each
meter with "tells" to indicate the occurrence of
tampering.

meter inspection system.

embodiment for a remote postage meter inspection system.
Detailed ~escription of the Preferred ~mbodiments
A postage meter inspection system has been devised
that reduces the need for on site inspection. Referring
to Fig. 1, a preferred embodiment will be described that
allows the inspection of a postage meter remotely. Such
a remote postage meter inspection system is shown
generally at 10 and includes a central station 12. This
central station 12 may be either a Post Office or the
office of a postage meter manufacturer. Included within
the central station 12 is a processor 1~ that is in
communication with a memory 16. This memory 16 would
include all the postage meters that are to be serviced
by the central processing s~ation 12 and would contain
information such as a meter number or customer number,
the date of last inspection, the name of the user and
any other pertinen~ information such as any history of
~637~;3
prior tampering. By tampering is meant any activity that
appears to in~olve the obtaining of fraudulent postage, i.e.
the applying of postage to a mail piece without paying or
accounting for the same. Also connected to the processor 14
would be a second memory 18 wherein a record of meters that
are to be inspected for any given period would be stored.
Obviously, these two memories 16,18 could be combined into
one if so desired. The central processor 14 is in
communication with a communication link or port such as a
modem 20 which in turn is in communication with a
communication device such as a telephone 22. A postag~
meter user location 24 would include a communication port,
such as a modem 26, that would provide connection between
the telephone 22 and a CPU 28. When a postage meter at the
user location 24 is to be inspected, communication would be
made with the user location by telephone 22 through the
modem 26. Alternatively, an inspection may be made
simultaneously when remotely recharging a postage meter by
having tampering information sent automatically to the
central station 12.
The CPU 28 is electrically connected to an electronic
postage meter 30 which has a CPU 32 and a memory 34
communicating directly with the CPU of the postage meter.
~lthough this embodiment shows only one postage meter 30 in
communication with the CPU 28, it will be appreciated that a
plurality of postage meters may be connected to the CPU 28
in network fashion. The postage meter 30 has a number of
sensors 36 that are in contact with the memory 34. Any
attempt of tampering would be sensed by the sensors 36,
which, in turn, would communicate such sensing to the memory
34 where a flag would be set. Upon command, the memory 34
would be accessed and a determination made whether a flag
had been set which would be an indication of tampering.
Such accessing could take place in accordance during power-
up of the postage meter 30.
With such a system 10, a number of meters would be
assigned for inspection during any given period and each
group of meters to be inspected would be supplied through
the memory 16. The central station 12 would then be in
~2~37~3
--4--
touch with the user station 24 indicating that inspection is
to take place. Th~ processor 14 of the central station 12
would then directly contact the CPU 32 of the postage meter
30 without any inter~ention or inter~erence on the part of
the user. The memory 34 of the postage meter 30 would be
scanned to determine if any of the sensors 36 sensed any
unusual activity. For example, if an attempt had been made
to remove the postage meter cover or a break off screw is
broken, an appropriate signal would be received by the
central station 12. Another check to be made is whether the
sum of the ascending and descending registers equals the
control sum. If any indication of tampering is received, a
message would be sent to the memory 18 and the meter 30
would be disabled upon command of the processor 14. A print
out would show all the postage meters 30 that did not pass
the electronic inspection and each of these would be
physically inspected. Additionally, the ~act that a
physical inspection was required for a meter would be stored
in the memory 18 so that if a large number of inspections
were required over a predetermined period, the meter could
either be replaced or the user questioned as to the reason
for the fre~uency of such physical inspection requirement.
Referring now to Fig. 2, an alternate embodiment of the
invention will be described. A central station 40, which
again may be either a Post Office or a postage meter
manufacturer, includes a computer data base ~2 which stores
the postage meter information, a printer station 44 and a
scanner 46. Periodically, the computer data base 42 will
cause the printer station 44 to send a mail piece such as a
post card 47 to one of a number of customer or user
locations 48. The post card 47 would be received by the
postage meter user and a postage indicia would be printed by
th user's postage meter 50. The user's postage meter 50
would be programmed so that any tampering would be sensed by
sensors 36 and these sensors would send an appropria~e
signal to the memory 52. In response to these signals, the
memory would cause alterations in ~he postage indicia, eacn
alteration being indicative of a particular sensor. Postage
meters having printers capable of variable printing and
3~753
capable of producin~ an altered indicia are shown and
described in co-pending Canadian patent applic~tions having serial
numbers 459,201 and 476,242. The alterations in the pattern
of printing by the postage meter are referred to as "tells".
A "tell" may be a modified indicia, number, letter, bar code
and the like. The postage meter 50 would print a postage
indicia with tells if any sensor indicated that tampering
had taken place or if the sum of the ascending and
descending registers did not e~ual the control sum. The
post card 47 printed with the appropriate postage indicia
would then be returned ~o the central station 40 and scanned
by the scanner 46. If the scanner finds that there has been
any tampering, this would be communicated to the computer
data base 42 and the central station operator would cause a
l~ physical inspection to take place. If no inspection is
required, this would also be communicated to the memory of
the data base 42.
